Pointless metadata events

[lsiepel]

The openHAB binding is using the zwave-js-server and receives many events. There is one event type that i don;t understand. The metadata updated event is triggered so many times but does not seem to hold anychange, atleast i have not yet found any event that had changes to the previous event. And i have log files with 10k+ events.

I wonder what the exact purpose is of this event.
If there is no use, can we filter it out, or if it does have a use, limit the events to exactly that use-case ?

Any chance you have the Z-Wave logs prior to this aswell, so I can reproduce?

An example i just noticed after i upgraded. The event from the ZUI client:

2025-10-21 14:07:07.220 [TRACE] [g.zwavejs.internal.api.ZWaveJSClient] - RECV | {"type":"event","event":{"source":"node","event":"metadata updated","nodeId":51,"args":{"commandClassName":"Meter","commandClass":50,"endpoint":0,"property":"value","propertyKey":65537,"metadata":{"type":"number","readable":true,"writeable":false,"label":"Electric Consumption [kWh]","ccSpecific":{"meterType":1,"scale":0,"rateType":1},"unit":"kWh","stateful":true,"secret":false},"propertyName":"value","propertyKeyName":"Electric_kWh_Consumed","nodeId":51}}}

The log file:

The file seems to be empty

Somehow my logs where empty / disabled.

I enabled it and allmost instantly had anopther occurence:

2025-10-21 14:52:07.734 [TRACE] [g.zwavejs.internal.api.ZWaveJSClient] - RECV | {"type":"event","event":{"source":"node","event":"metadata updated","nodeId":51,"args":{"commandClassName":"Meter","commandClass":50,"endpoint":0,"property":"value","propertyKey":66817,"metadata":{"type":"number","readable":true,"writeable":false,"label":"Electric Consumption [A]","ccSpecific":{"meterType":1,"scale":5,"rateType":1},"unit":"A","stateful":true,"secret":false},"propertyName":"value","propertyKeyName":"Electric_A_Consumed","nodeId":51}}}

Those are the wrong logs unfortunately. I need the driver logs which show the network traffic on loglevel debug:
